UNITED STATES PATENT OFFICE.

SAMUEL D. NIMS, OF PALMER, MASSACHUSETTS.

METHOD OF HANGING WINDOW-SASHES.

Specification of Letters Patent No. 8,611, dated December 23, 1851.

To all whom t may concern Be it known that I, SAMUEL D. NiMS, of Palmer,in the county of Hampden and State of Massachusetts, have invented a newand Improved Manner of Arranging and Securing findowSa-shes within TheirFrames; and I do hereby declare that the following is a full and eXactdescription thereof, refer ence being had to the accompanying drawings,making part of this specilication, in whichl Figure l, is a frontelevation of a window constructed in my improved manner; Fig. 2, avertical section of the same, in the line ai, of Fig. l, the sashes andpart of the window frame being removed; Fig. 3, horizontal section ofthe same, in the line y, of Fig. 1; and Fig. Il, a perspective view o-fa portion dej tached.

Like parts are designated by similar letters in all the figures.

I construct the window frame and sashes in the usual manner; but insteadof securing the sash in its frame by means of the common slats, I makeuseof grooves c, c, either in the window frame or edge of the sashes A,A', into which corresponding projections on the adjacent part of thesashes or frame fit accurately. One side of the window frame is firm,and the other side I make elastic and yielding by means of the followingdevice. In one side of the window frame B, is a recess, into which amovable piece C, is accurately fitted. Said piece should be thin enoughto allow its being sunk into the recess of the window frame forinserting and removing the sashes, which fit into it by means of groovesand projections c, c, the same as above described. Behind the aforesaidpiece C, are springs a, a, which press it against the window sashes withsufficient force to hold them securely and tightly in the frame, andalso to keep them in place, when raised or lowered, if desired.

When the sash is to be inserted in, or taken from its frame, one side ispressed against the movable piece C, forcing back its springs a, a,which allow the sash to pass into or out of the grooves or projectionsof the opposite side of the window frame, and hold it in them whenintroduced. Should said springs a, a, be so strong as to make itinconvenient to remove or insert the sashes, the sliding bolts b, are tobe used to hold the piece O, back until the sashes are removed orinserted in their places.

By my above described improved manner of constructing windows, thesashes can be put in or taken out in a few seconds. They are also heldup in any position without any additional contrivance. Another advantageis that the window is rendered air-tight, and no inconvenience arisesfrom the wood swelling in damp weather. It also is free from rattling bythe wind or other cause, a quality which renders it peculiarly adaptedto railroad cars.

I am aware that strips acted upon by springs, have been placed ingrooves in window sashes, and also in grooves in the casing for actingon the sashes for the purpose of excluding air and for sustaining thesashes when raised, in place of weights, and therefore, I wish it to beunderstood that I do not claim the said arrangement as any part of myinvention. But

What I do claim as my invention and desire to secure by Letters Patent,is

The manner herein described of arranging and securing window sashes intheir frames, by means of grooves c, c, in the sides ((1,) of the windowframe (or casing) that receive the edges of the sashes, (or byprojections from the'sdes of said frame or casing that fit into groovesin the edges of the sashes;) and by making one or both sides of thewindow frame, or casing, movable and elastic by means of the springs a,a, or their equivalents.

The above specification of my improved manner of arranging and securingwindow sashes within their frames-signed this 13th day of Nov., 1851.
